  <p>gluon.rewrite parses incoming URLs and formats outgoing URLs for 
  gluon.html.URL.</p>
  <p>In addition, it rewrites both incoming and outgoing URLs based on the 
  (optional) user-supplied routes.py, which also allows for rewriting of 
  certain error messages.</p>
  routes.py supports two styles of URL rewriting, depending on whether 
  'routers' is defined. Refer to router.example.py and routes.example.py 
  for additional documentation.<br /><br />

supply /a/c/f (or /a/lang/c/f) portion of outgoing url

The basic rule is that we can only make transformations
that map_url_in can reverse.

Suppose that the incoming arguments are a,c,f,args,lang
and that the router defaults are da, dc, df, dl.

We can perform these transformations trivially if args=[] and lang=None or dl:

/da/dc/df =&gt; /
/a/dc/df =&gt; /a
/a/c/df =&gt; /a/c

We would also like to be able to strip the default application or application/controller
from URLs with function/args present, thus:

    /da/c/f/args  =&gt; /c/f/args
    /da/dc/f/args =&gt; /f/args

We use [applications] and [controllers] to suppress ambiguous omissions.

We assume that language names do not collide with a/c/f names.
